(A) Step length of Slip01_Rec1 and Slip10_Rec1 compared with Normal (average ± SD as error bars); *: significantly shorter than Normal, p < 0.001; ‡: Slip10 significantly longer than Slip01, p < 0.001; n.s.: no significant difference between conditions. See Supplementary Figure 8 for participants' data points. (B) Correlation between step length in Slip01_Rec1 and MoS of Slip01_Rec2 (r = 0.648, p < 0.001). Black circles: young adults; grey circles: older adults. (C) Correlation between step length in Slip01_Rec1 and n_steps (first of at least three consecutive steps within one standard deviation of normal MoS) in Slip01 (Spearman's rho = −0.480, p = 0.004), participants whose n_steps had not returned to Normal by Rec15 were removed from the correlation analysis. Black circles: young adults; grey circles: older adults. % BH: % of body height.
